Marc was born to parents who worked in a seed company in Iowa. He graduated from the University of Illinois with a degree of computer science. In one summer, he interned at IBM in Texas. Later, he worked at the National Center for Supercomputing Applications (NCSA) where he met Eric Bina with whom he collaborated to produce Mosaic, one of the first web browsers to be widely used by the public.

In the early 1990s, he co-founded Netscape Communications with Jim Clark who foresaw the commercial possibilities of the web browser. The resulting product of the company was called Netscape Navigator in order to avoid legal complication with NCSA who claimed ownership of Mosaic. The company went public in 1995 and Marc became an overnight billionaire and celebrity with his face on the cover of Time magazine and other publications.

In 1999, Netscape was sold to AOL for $4.2 billion and Marc was designated as the Chief Technology Officer. When he left AOL, he formed a web-hosting company called LoudCloud. When the hosting business was sold to EDS, it changed its name to Opsware which was in turn sold to Hewlett-Packard for $1.6 billion.

Marc went on to set up a venture capital firm with Ben Horowitz in 2009. They have invested in such firms as Twitter, facebook, Zynga, Pinterest, Jawbone, Skype, Instagram and many other start-ups. He had been appointed to become member of the board of these companies.

Marc is married to Laura Arrillaga, the daughter of another Silicon Valley billionaire. They have a son named John.
